Abstract
The present invention is directed to an improved design and improved method of installation of stress absorbing membrane interlayers, commonly known as SAMIs, used for strengthening and waterproofing asphalt pavements in road or highway surfacing operations. By a novel method of modifying a standard paving machine the present invention makes it easier and more convenient to install SAMI membranes beneath a layer of new asphalt pavement, thus providing greater resistance to pavement cracking resulting in lower overall maintenance costs.
Claims12
Modifications made to an asphalt paving machine which modifications consists of one or a plurality of mounted membrane dispensing shafts which said shafts can hold and allow the dispensing of a pavement reinforcing membrane continuously beneath a paving machine as it moves forward.
A Novel Method of asphalt paving whereby an asphalt paving machine with special membrane dispensing can continuously dispense a pavement reinforcing membrane onto a surface and concurrently dispense hot paving mix onto the said membrane as it moves forward.
A Novel pavement reinforcing membrane supplied as rolls and produced by hot-coating and sand surfacing both faces of a non-woven polymer fiber reinforcement sheet with an elastomeric modified asphalt bitumen coating which is formulated to have a heat-activated bonding surface.
