Daur ulang bahan garukan beton tambah semen merupakan suatu upaya untuk mendapatkan bahan baru yang diperoleh dari pemanfaatan bahan garukan perkerasan yang sudah menurun kualitasnya karena faktor umur atau kerusakan perkerasan. Pada penelitian daur ulang ini, bahan garukan beton aspal diasumsikan sebagai agregat sehingga kadar aspal yang terkandung pada bahan garukan tidak diperhitungkan. Seba…

Trr No. 1171 Asphalt Materials And Mixtures, pp. 12-17 The modifiedx version is a practical substitute for its former version that was based on longer immersion periods (up to 14 days) and a greater number of sample sets (five versus three neede by the current procedure). The development of the test was supported by laboratory and initial field experience, as well as by theoretical considerati…
Trr No. 1171 Asphalt Materials And Mixtures, pp. 113-120 Rubber modified asphalt pavement mixtures have been used in Sweden and The US. In these applications ground, recycled tyre particles are added to a gap graded aggregate and then mixed with hot asphalt cement. The benefits of adding rubber to the mix include increased skid resistance, elimination of a solid waste, and reduce traffic noi…

Trr No. 1311 Pavement Design, Management And Performance, pp. 120-130 Digital image processing and pattern recognition from a video log of pavement surface distress is accomplished by initializing the image prcessing board within an IBM-PC (or compatible). Software is used to set all image processing registers to zero or a default value, which digitizes values for each color (0 to 255), and se…
Trr No. 1311 Pavement Design, Management And Performance, pp. 144-148 Automated pavement surface distress evaluation would be a useful component of computerized pavement management systems. Methods are described for applying computer simulations of pavement distress appearance to the design of those evaluation systems. By generalizing the results of crack visibility calculations under varying …
