Instant Concrete Road Repair Solution

The Durability of road structures depends on the quality of its maintenance & minor renovations. Maintenance keeps the roadway safe, provides good driving conditions & prolongs the life of the pavement, thus protecting the road investment.

Currently in India more than 2000 km of concrete road is in the operation since last few years. Most of the projects completed by NHAI, MSRDC and other state government authorities.

Though the quality & procedural aspects, specifications / guidelines clearly mentions in IRC, MoRTH, but still we observes that various minor cracks, potholes and joints edge spalling in the PQC due to various factors which requires maintenance.

Maintenance includes the prompt sealing of cracks & filling of potholes to prevent water entering through the surface.

Repairs and rehabilitation of concrete roads are required to have a smooth riding quality as well as avoid inconvenience causing to the vehicles.

We need to have a durable repair products to avoid of cost of various factors like :
a) Diverting the traffic for repairs
b) Inconvenience to the traffic
c) Repeatedly cost of repairs by using conventional methods.

Curating Restlessness: Regulating Landscapes of Change

The research Proposal by Michael Ippolito from the California College of the Arts proposes a radical rethinking of architecture and landslides. The Marin Headlands is home to over twenty landslides. The most notable and fastest acting landslide in the Headlands is located on the Oceanside of the park between rodeo cove and Tennessee Valley. It is known as place that has been left behind and rendered a volatile wasteland. This wasteland has consumed many man-made structures including eight abandoned military buildings, and two roadways.

The DISPENS(FILTRATOR) proposal renders the existing landslide to be inhabited by an architecture that filtrates the landscape for scientist, students, and recreationist. There are three major components of the DISPENS[FILTRATOR] ; one: the harvesting zone that filtrates boulders, rocks, soil, and water into four different levels, two: the recreational zone that dispenses recreational mechanisms such as the stargazer, climbing cage, and nature watcher, and three: the collection zone (after life) where the mechanisms are collected and jumbled into an artificial habitat where plant and animal life can thrive.

The DISPENSFILTRATOR is an architecture that curates the environment and blurs the distinction between BUILDING, LANDSCAPE, and WASTELAND. This radical rethinking of architecture and landslides allows the populations that visit these kinds of sites to experience a heightened awareness of savvy inhabitance for increasingly dynamic landscapes.

India’s 11 Super Expressways

India, a developing country has world’s third largest road network but when we talk about expressways, we can hardly name a few like Mumbai-Pune Expressway and Delhi-Gurgaon Expressway. So we decided to tell you about some of the other expressways in India.

Here is the list of India’s top 11 Super Expressways

1) Ahmedabad Vadodara Expressway
Ahmedabad Vadodara Expressway is 95 km long and joins Ahmedabad and Baroda in Gujarat. It is also referred as National Expressway 1. This expressway was opened to public in 2004 and was constructed under the Golden Quadrilateral Project by NHAI.

2) Mumbai-Pune Expressway
Mumbai-Pune Expressway (official name is the Yashwantrao Chavan Expressway) is 93 km long and is considered as one of the best expressways in India. It is India’s first six lane high speed expressway and was made by Maharashtra State Road Development Corporation (MSRDC) at a staggering cost of Rs 1,630 crore (US$363.49 million). It was opened to public in April 2002

3) Jaipur-Kishangarh Expressway
Jaipur-Kishangarh Expressway is 90km long and it connects Jaipur with Kishangarh. It was constructed under the Golden Quadrilateral National Highways Development Project and its cost was USD 154 million. More than 20,000 vehicles pass from this highway everyday.

4) Allahabad Bypass
Allahabad Bypass covers a distance of 86 km and is one of the most remarkable achievements of the Golden Quadrilateral project. It connects India’s four main metropolians New Delhi, Kolkata, Mumbai and Chennai.

5) Ambala Chandigarh Expressway
Ambala Chandigarh Expressway covers a distance of 35 km and has reduced the traffic congestion to a much greater extent. It was opened in 2009 and was built at a cost of Rs 298 crore ($66.45 million)

6) Chennai Bypass
Chennai Bypass covers a distance of 32 km and connects four national highways (NH45, NH4, NH205 and NH5) around Chennai. The cost of this project was Rs 405 crore (Rs 4.05 billion).

7) Delhi-Gurgaon Expressway
Delhi-Gurgaon Expressway covers a distance of 28 km and has been a life saver for commuters. Before construction of this expressway huge traffic jams were seen on the roads. Though this problem has not been solved 100% but still this expressway has brought some relief to the commuters. Delhi-Gurgaon Expressway starts at Dhaula Kuan in Delhi and ends at Manesar which is on the outskirts of Gurgaon. The cost of this project was $223 million and it was opened for public use in January 2008.

8 ) Noida-Greater Noida Expressway
Noida-Greater Noida Expressway covers a distance of 24.53 km. This six-lane highway connects Noida to Greater Noida. The total cost to build this expressway is about 400 crores (Rs 4 billion).

9) Delhi Noida Direct Flyway
Delhi Noida Direct Flyway or popularly known as the DND flyway is an eight lane road having a total length of 9.2 km and connects Delhi to Noida. It was built by The Noida Toll Bridge Company Ltd.

10) Hyderabad elevated expressway
Two separate elevated expressways were to be constructed in Hyderabad to overcome the congestion problem. The first one is P.V. Narasimha Rao Elevated Expressway which covers a distance of 11.6 km and the other Rajiv Elevated Expressway which will cover the distance of 20 km. P.V. Narasimha Rao Elevated Expressway was completed in 2009 and it connects Hyderabad International Airport to Mehdipatnam. Rajiv Elevated Expressway was proposed as an extension and will cover Secunderabad-Shamirpet stretch via Karkhana, Trimulgherry and Bollarum. But this project is currently under suspension due to high project costs.

11) Hosur Road Elevated Expressway
Hosur Road Elevated Expressway covers a distance of 9.98 km and connects Bangalore to Hosur. This expressway has the distinction of becoming the tallest expressway in Bangalore at the height of 17 meters i.e. 56 ft. This project was started in 2006 by BETL and was inaugurated on 22 January 2010.
We have many more expressways in India which are under construction or are already approved but work has not started yet. But still India needs many more of those expressways, to reduce the traveling time and for better connectivity across other Indian cities and states.
