Water can penetrate the small cracks in bitumen roads and weaken the structure by eroding the base layers, leading to potholes and pavement failure. Additionally, water can cause the bitumen to soften and lose its binding properties, reducing the road's durability and strength over time.

What are physical properties of bitumen?
Bitumen is a black or dark-colored solid or semi-solid material that is sticky, water-resistant, and highly viscous. It is insoluble in water but soluble in carbon disulfide and carbon tetrachloride. Bitumen has a high melting point and can soften when heated.
What is double bitumen surface treatment?
Double bitumen surface treatment is a road maintenance technique that involves applying two layers of bitumen emulsion and aggregate to enhance the surface of a road. The process typically includes first applying a bitumen layer, followed by spreading aggregate, then a second layer of bitumen and more aggregate. This treatment improves the road's durability, skid resistance, and overall performance while extending its lifespan. It is often used on existing roads to restore surface quality without the need for extensive reconstruction.
What is another name for bitumen?
Typically, bitumen and "asphalt" are interchangeable.
When to use ki70 bitumen?
Ki70 bitumen is commonly used for surface dressing applications, tack coats, and as a binder in asphalt mixtures. It is especially suitable for road construction and repair projects where a durable and weather-resistant pavement is required. Its properties make it ideal for enhancing the longevity and performance of roads.
What is the difference between bitumen and crude oil?

Can bitumen be mixed with acrylic solutions to make it water resistant?
Yes. Bitumen is already water resistant - it is a mixture of long chain polymers, many of which are asphaltic. You can make acrylic bitumen emulsions which are water dispersible but which, when cured (dried) have the same (or similar) water resistance as pure bitumen.
Is bitumen harmful to sheep i need to repair a hole in a water trough?
If the sheep eat the bitumen yes it can be harmful and the chemicals in the bitumen would eventually leech out and contaminate the water.
What is the difference between cutback bitumen and bitumen emulsion?
Cut-back bitumen uses solvent as the mixing medium where in Emulsion uses water to dilute bitumen for the purpose of tack-coating / road works
Why roads are in black colour?
Black is the colour of the tar used to surface the road. Tar and bitumen are two important binders for road making. Tar is a by- product of coke and bitumen come from refining crude petroleum.
Can sandstorms destroy roads?
Really serious sandstorms may not destroy roads but they can bury them, requiring a cleaning before they can open to traffic again.
EFFECT of OIL on ASPHALT?
Depends on type and quantity of oil, but it tends to dissolve the bitumen binder and so destroy the asphalt.
