THE INFLUENCE OF A PLASTIC FABRIC UPON THE PAVEMENT AT FROST BREAK

The present report deals with an investigation into the influence of a plastic fabric upon the properties of a road pavement when thaw begins, when the fabric is introduced as a protective layer in the pavement. The properties studied were material migration, bearing capacity and fatigue life at repeated loading. Three types of pavements were studied: conventional pavement with granular road base, crushed rock pavement and strengthened gravel road, all having A bituminous wearing course. In the crushed rock pavement comparison was made between a sand filter layer and A fabric. The results showed material migration only in the pavement having an unprotected gravel wearing course, which migrated into the overlay. No influence upon the deflection at static load due to the absence or presence of the fabric could be ascertained. Pavements with a protective fabric showed longer fatigue life than the similar pavement without fabric. The fabric showed signs of damage only at introduction of crushed rock, whose sharp edges could cause puncture. /Author/TRRL/
