PERFORMANCE AND DURABILITY OF BITUMINOUS MATERIALS. 7: AN EVALUATION OF THE USE OF A FIBRE-REINFORCED MEMBRANE TO INHIBIT REFLECTIVE CRACKING

Reflective cracking in bituminous pavements occurs through thermal and traffic induced fatigue, and there are many solutions available to the maintenance engineer to prevent or inhibit crack initiation on the road surface. Much has been written about these causes and solutions and this review attempts to take into account current thinking, concluding that there is much confusion about where, when and which type of treatment for reflective cracking should be specified. Through a summary of recent market and technical research, this paper reviews the use of stress absorbing membrane interlayers (SAMI's) in the UK and evaluates the use of a fibre-reinforced membrane as an effective and efficient alternative to conventional geotextiles and geogrids. The fibre-reinforced membrane is manufactured in-situ and spray-applied through specially developed equipment to achieve a continuous, waterproof and flexible mat, capable of inhibiting reflective cracking. The characteristics and technical performance of this membrane are explored. It is concluded that the use of the membrane as described in this paper, meets an engineer's need for a practical, economic and speedy solution to inhibit reflective cracking in bituminous pavements.
