       Notes - general: This report describes the construction of a trial on
                        the A30 trunk road at Bodmin Bypass to assess the
                        ability of three types of geotextile to minimise the
                        development of reflection cracking in an asphalt
                        overlay on a flexible composite road.  Hot rolled
                        asphaltoverlays of 40mm and 80mm thickness were laid
                        over the geotextiles.  In addition, one test section
                        was constructed in which five proprietary
                        crack-inhibiting treatments were applied to individual
                        cracks before overlaying with 40mm of hot rolled
                        asphalt.  Details are given of visal condition surveys
                        and Falling-Weight-Deflectometer measurements to
                        assess the severity of the cracks being treated.
