       Notes - general: A laboratory investigation and full-scale trial of
                        Chemcrete U1-49 in a low-stability hot rolled asphalt
                        are described.  In laboratory tests, the addition of
                        2% of Checrete U1-49 resulted in improvements to
                        stability, modulus and wheel-tracking rate.  In a
                        full-scale road trial, the same ashpalt mix with
                        Chemcrete in 70% bitumen was laid satisfactorily under
                        adverse weather conditions and, after 1 year, the test
                        section showed superior rutting and retention of
                        texture compared with a control material using an
                        unmodified 70 pen bitumen; after this period of time
                        the Chemcrete materials were not apparently fully
                        cured.
