UltraTech’s white topping concrete for durable, aesthetic roads UltraTech Concrete, a division of UltraTech Cement Ltd, and India’s largest manufacturer of ready mix concrete (RMC) recently supplied white topping concrete for the Nandi Infrastructure Corridor Enterprise (NICE) Road in Bengaluru, Karnataka. The 9.5 km link road and 4 km peripheral road will connect the proposed 111 km Bengaluru-Mysore Industrial Corridor (BMIC) expressway which is expected to reduce the 3-hour drive between the two cities to an hour. White topping is the covering of an existing asphalt road with a layer of Portland cement concrete. It can be used on road surfaces where traditional asphalt surfaces have failed due to rutting or general deterioration. White topping concrete is known to improve the performance, durability and ride quality of road surfaces. While the lifespan of ordinary bitumen roads is 5-10 years, the designed service life of white topping concrete surfaces is around 2530 years, and includes minimum maintenance cost. It ensures faster

moving traffic due to improved ride quality and skid resistance. White topping is considered energy efficient as it saves 20-30 per cent energy required for illumination due to better reflectivity. This property also helps to reduce accidents, especially during nights. Further, it is 100 per cent

recyclable after its service life, making it a green choice. “White topping concrete represents an important potential application area from a sustainability perspective. With non-renewable resources such as fossil fuels and quarry-aggregates decreasing in availability, it is important

Cabinet nod to convert 7,200 km state roads to highways The Centre has decided to convert 7,200 km of state roads into national highways. “The Cabinet Committee on Economic Affairs (CCEA) has given nod for declaring 7,200 km state highways as national highways,” said a senior minister. With this the total length of state highways converted into national highways during the UPA regime would reach about 17,000 km. About 10,000 km of state highways were declared national highways during the past 10 years. These roads, sources said, are spread across states including Andhra Pradesh, Madhya Pradesh, Bihar and Uttar Pradesh besides

to begin making decisions based on sustainability rather than on a first cost basis. “White topping concrete overlays/ pavements are a cost-effective, sustainable choice for urban roads, state and national highways, and other pavement applications,” says

bordering areas like Leh and Laddakh regions. The present length of national highways in the country is about 80,000 km. Meanwhile, an official statement said there would be sufficient funds to take up improvement on new national highways. “Keeping in view the estimated allocations likely to be made available for development of nonNHDP national highways based on the previous years’ trends, it is anticipated that there would be adequate funds available for taking up improvement works on these new NHs,” it said. The National Highways

Development Project (NHDP) is the flagship road building programme of the Ministry of Road Transport & Highways, currently running into seven phases. It added that there would also be adequate funds available for taking up improvement of the remaining existing NH network of 21,271 km, not covered under any programme so far. The statement said expansion of NH network is a continuous process and declaration of a new NH is taken up from time to time, depending up on requirement of connectivity, inter-se priority and availability of funds.

BASF’s Green Sense Concrete technology for Europe BASF now offers its Green Sense Concrete technology for the resource- efficient production and processing of concrete in Europe as well. Green Sense Concrete is a service package from BASF that helps manufacturers improve performance characteristics of concrete such as resilience, workability, durability and environment friendliness. The package comprises three components: The optimization of the concrete mix design by BASF experts, the use of hyper plasticizers from BASF such as MasterGlenium, and an eco-efficiency analysis of the concrete mix. The analysis serves to ascertain economic and ecological


Floor protection during construction Reasons for introduction of floor protection product. While doing the interiors of any project, flooring is completed prior to electrical or plumbing work. During these works, scratches can develop, even resulting in breaking of tiles/ flooring due to dragging of heavy equipment. As 25 per cent of the interior cost involves modern floorings, it is necessary to protect floors till total interior work is completed. Traditionally, Plaster of Paris (PoP) was used for this particular application, but not only laying and removing of PoP is a time-consuming and a tedious activity, but it also generates harmful dust. What are the salient features of the product? DURA floor protector is an innovative technology that provides universal cushioned flooring protection for wood, ceramic and vinyl floors. It is a closed-cell; polymer-
