A damp proof course ( dpc ) is a physical barrier inserted into the fabric of a building to stop water passing from one place to another. This can be on a horizontal plane, stopping water rising up from the ground by being sucked up by the dry masonry above, or vertically to stop water passing from the outside of a building, though the masonry, to the inside. Dpc's have taken many forms through the ages and one of the earliest forms was to use a layer of slate in the construction. Slate is still used but the less expensive plastic version ( below right ) is now more widely used.

The term bitumen refers to a substance produced through the distillation of crude oil. Bitumen is known for its waterproofing and adhesive properties and is commonly used in the construction industry, notably for roads and highways. The two Bitumen grades are 60/70 and 80/100. The difference between 60/70 and 80/100 penetration grade is the penetration range.� Bitumen 60/70 has lower penetration which means it is harder than bitumen 80/100. Bitumen 60/70 is better suited for use in hot climates and can withstand heavy traffic loads, unlike bitumen 80/100. According to the ASTM D36 method,� the softening point of bitumen 60/70 is between 49 to 56�°C, and the flash point of bitumen 60/70 is 250 �°C. Another important factor is density. Due to the ASTM D70, the density of bitumen 60/70 is equal to 1.0344. Bitumen Penetration Grade 85/100 is� a standard penetration grade. Bitumen usually used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties. This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.
Bitumen is used in road construction due to various properties and advantages. The bitumen as a raw material in flexible road construction and bitumen as a mix (composing other materials i.e. aggregates etc.) serves certain advantages, that prompt to use bitumen widely in road construction. An overall bitumen mix is used in the construction of flexible pavement to serve the following needs Structural Strength Surface Drainage Surface Friction
