HIGHWAYS AND ROADWAYS products
- Polymer Modified Bitumen
- HMVG 40
- Shelmac PR™
Specially engineered Polymer Modified Bitumen (PMB) is a proven solution to deal with the pressures exerted on today’s highways.
Its benefits are as follows:
- Improved rheology – elasticity recovery and viscosity
- Reduced chances of fatigue cracking
- Improved fuel resistance
- Improved adhesion/cohesion
Shell Cariphalte has been used to pave major highways including: A20 motorway, A2 motorway (Germany), A54 motorway (France), E17 motorway (Belgium), M25, M6 Toll, A38, A14, M1 (UK), Chang’an Avenue (China).
Cold application of bitumen requires less energy, resulting in reduced emissions and a lower product impact on the environment. Shell Spramul has been developed for cold application of binder in a spray or for mixing with fine to coarse graded aggregates, making it highly effective for crack, slurry sealing and micro surfacing.
With its lower viscosity and ability to cover a wider area, Shell Spramul helps you meet construction timelines, all while delivering pavement performance. Also, its cold application requires less energy, resulting in reduced emissions. It can be stored long-term without migration or loss of properties.
Discussions around sustainability, conservation of natural resources are growing. The utilisation of scrap tyres in rubber-modified bitumen (RMB) can not only help contribute to the conservation of natural resources and improved waste management but also enable the creation of high-performing asphalt pavements, comparable to those containing polymer modified bitumen (PMB).
Shell Mexphalte RM is an innovative RMB designed to provide high performance for long-lasting pavements; hence it can help meet increasing traffic load demands. In addition, it can help contribute to better waste management.
With the ever-increasing traffic and increase in axle loads, highways require high resistance to surface tensile stresses. Therefore, HMVG-40, High Quality Viscosity Grade Paving Bitumen is manufactured using patented technology, keeping in mind the needs of modern highways. The use of Harder Grade Binder HMVG-40 in bituminous mixes offers following benefits over conventional Bitumen.
- Production of rut as well as fatigue resistant mix
- Production of mixes with high resilient modulus
- Reduction in bottom-up cracking
- High resistance to surface tensile stresses under heavy axle loads on high-volume roads
- Reduction in the overall pavement thickness
- Lowering susceptibility to daily and seasonal temperature variations
- Delay in maintenance/resurfacing, resulting in long-term cost saving
Shelmac PR™ is a ready to use pre-mix, which provides a long lasting solution to potholes and depressions on the roads. Shelmac PR™ is a cold applied solution which consists of aggregates of 10mm and lower sizes.These graded aggregates ensure optimal aggregate interlock after placement and hence, possess good resistance to deformation under traffic.
It eliminates the need for plant and machinery at site, utilizes minimum unskilled labor. Post repair, roads can be reopened to heavy traffic immediately.
It Offers no sticking/picking-up of material by vehicle tyres or water which leads to increased service life of the potholes with very little or no raveling, bleeding or depression.
- Polymer Modified Bitumen
Specially engineered Polymer Modified Bitumen (PMB) is a proven solution to deal with the pressures exerted on today’s highways. Its benefits include:
These concrete and asphalt surface joint sealants are especially resistant to expansion and contraction stresses, compression and cyclic movements in horizontal joints. They adhere well to the surface and can withstand pavement movements without losing their adhesive qualities. Fuel, oil and fire-resistant, they also resist deterioration by weathering, sunlight, ozone, water and salt.
The sealants are available in two variants – a hot poured sealant ideal for concrete surfaces (Jointseal) and an ambient temperature pouring-grade elastomeric sealant (Polyseal).
