Techno Anti Stripping Agent As Per IS 14982 / 2001 & MORT & H REF. MANUAL
Techno Anti Stripping Agent is a specially formulated compound for improvement of adhesion between Bitumen & Aggregates so as to avoid stripping of Bitumen on aggregates. It strengthens the bond between Bitumen & Aggregates which will not be dislodged by water
Requirement Of Techno Anti Stripping Agent
• One of the most common problems faced by highway departments is stripping.
• Stripping usually occur when there is a loss of adhesion between the aggregate and the asphalt binder.
• Sometimes it may also be due to cohesion within the asphalt binder itself.
• These problems ensue due to a lot of factors and one of them is exposure to natural elements such as heat, rain and snow. It also includes wear and tear due to traffic and aging.
• Although non-stripping asphalt has not been produced, there are measures that can be applied to prolong the life span of our highways. Today, there are a wide variety of anti-stripping agents which can be used to make the asphalt more durable.
• Anti-strip additives or ASAs come in a variety of compositions which greatly varies from each other.
• Some ASAs come in liquid form while others come in a powder form just like cement.
• There are a lot of reasons why a pavement or asphalt gets stripped. Some of these are weak aggregate, too much void content or air bubbles, mixing temperature, storage, poor drainage, excessive dust coating and exposure to the elements. So far, the solution to this is to anti-stripping agents.
• Anti-stripping agents help keep the bond between the aggregate and the binder. In short it keeps the asphalt intact. Studies had shown that roadways threated with anti-strip compounds tend to last longer and be more resilient to the regular wear and tear as compared to pavements that were not treated with ASAs.
• They also exhibited greater resistance to moisture which is very significant as moisture is the prime suspect for causing road damage.
Advantage Of Using Techno Anti Stripping Agent
• Adding lime to the cement or asphalt mixture can be done by sprinkling the lime on top of the newly constructed pavement or by adding the powdered lime into the slurry while it is being mixed.
• Mixing lime with the slurry can cause excessive loss of lime even before the binder can be added while sprinkling them on the aggregate will not ensure an even coat.
• That is why liquid anti-strip agents are becoming more and more popular as there are liquid ASAs which comes in par with lime when it comes to toughening up a pavement.
Packing Of Techno Anti Stripping Agent
• In 200 Kg. New, A1- reconditioned mild steel drums with screw-type cap seal.
• It is also available in bulk tanker of 15, 20 & 24 MT.
• It can also be processed at site as per buyer’s requirement.
Techno Microsurfacing System
