The Challenges of Road Preservation Program for Indonesian National Roadway ARY Setyawan1, a *, AGUS Taufik Mulyono2,b 1Roadmate Research Group, Sebelas Maret University, Indonesia 2Civil Engineering and Environment Department, Gajahmada University, Indonesia acenase@yahoo.com, batm8002@yahoo.com Keywords: road, preservation, performance, contract.
The average usage rate of the general Indonesian National Standard (SNI), related to building construction materials, and the specific SNI, related to civil engineering, in road infrastructure contract documents are not more than 30.0% [6].
Internal factors that cause bad roads are always associated with accuracy how far the quality of the implementation of the road can be achieved, among other things: careful selection of materials, precision operate of the field equipment, precision quality testing and interpretation of the Detailed Engineering Design.

Experimental Study on the Crack Resistance of Waste Asphalt Concrete Fiber Cement Stabilized Macadam Hongbo LI 1, 2,3, a, Zhanjiang LIU 1,b, Hui SHEN 1, 2,3, c 1 College of Civil and Hydraulic Engineering, Ningxia University , Yinchuan 750021, China, 2 Ningxia Research Center of Technology on Water-saving Irrigation and Water Resources Management, Yinchuan 750021, China, 3 Engineering Research Center for Efficient Utilization of Water Resources in Modern Agriculture in Arid Regions.
Through mixing different amount of waste asphalt concrete, fiber and fly ash, to study how those factors improve the crack resistance of waste asphalt concrete fiber cement stabilized macadam materials on the basis of having no affect on its mechanical properties, so as to adapt to the requirements for material anti-cracking performance of engineering construction.
The common ways for actual situation of engineering like covering with thin film or wet grass mat, or wet curing by water spraying frequently, which plays an important role in preventing and reducing dry shrinkage crack.
Drying Shrinkage Test Drying Shrinkage Test Results The preparation and maintenance of test specimens and the drying shrinkage test are conducted in strict accordance with the relevant provisions in highway engineering stable inorganic binder material test procedures (JTG E51-2009), the specific drying shrinkage test data of each specimen in different time periods are shown in Table3.

According to the report on the exploration of the geological engineering, the formation lithology of the section (stake number from SH210+100 to SH210+773) from old to new is respectively the middle Pleistocene alluvial-pluvial layer (al+plQ2), the upper Pleistocene alluvial layer (alQ3), the holocene alluvial layer (alQ4).
So according to Standard for classification of engineering rock masses (GB 50218-94), design specification of highway tunnel(JTG D70-2004), code for designing on subsoil and foundation of highway bridge and culvert(JTG D63-2007), geotechnical engineering specification (GB 50021-2001), etc.
According to standard for engineering classification of rock masses (GB50218-94), we can classify the rigidity degree of the rocks by the rock-saturation and uniaxial compressive strength, the results can be seen in the Tab.2.
