Research Project [2] Comments
Administration and Contract Matter
The reseach project was signed on the end of March 2007 , between our Head of Research Board of UMY (LP3), Drs.Said Tuhuleley with the Directore of Research and Cummunity Services, Ministry of National Education Indonesia. The research proposal was approved for the first year from two years of proposed research duration. After completing the first year research, the team must present the result of first year and the selected reviewer from Ministry of National Education will assess the possibility for giving approval the continuous grant of research. The team must write all research activities in the log book for monitoring the progress, difficulties and problems (if any) and some alternative solutions that be used for consolidating the problems.
Model Development
In the research plan, the team must develop the 2-D and 3-D dynamic stiffness matrix model to be implemented for calculating the wave propagation simulation in the pavement. The inversion process used in this analytical stage for seismic data of SASW test on the pavement has chosen using the dynamic stiffness matrix and the optimization process using the maximum likelihood method (Joh 1996; Rosyidi 2004). The team has already simulated the algorithm and some results showed the stiffness matrix model can be used in the analysis. Currently, a member of the team, Dr.Handayani, is trying for simulating the fundamental model of wave propagations. While, Sri Atmaja P. Rosyidi is developing the integrated SASW system for pavement investigation together with its algorithm of wavelets, signals processing and application of inversion stages. Prof.Raihan is now, writing the analysis of wave in the pavement using FEM.
On Wednesday, June 21, 2007, our academic staff of LATEI and civil engineering lecturer in UMY, Sri Atmaja P. Rosyidi, presented his research work in International Conference on Advanced Characterisation of Pavement and Soil Engineering Materials (Athens 2007) in Athens, Greece. He, and together with 3 professors in Universiti Kebangsaan Malaysia and senior researcher from Puslitbang Bandung, wrote a paper entitled “Development of Vs-CBR-DCP empirical model for determining dynamic stiffness of pavement base layer using SASW”. His research produced the empirical model for measuring the dynamic and static stiffness using the spectral analysis of surface wave (SASW) method. The result showed that the SASW method has capability for assessing the road structural modulus and bearing capacity without any deteriorations on pavement, and the test can be performed fast and accurate.
Eight International Conference on the Bearing Capacity of Roads, Railways and Airfields

Call Paper
Call for abstract : Nov., 1, 2007
Deadline for receiving abstracts via email: Feb., 15, 2008
Conference website: www.BCR2A.org
This conference focuses on the causes, development, and maintenance / rehabilitation of pavement cracking, as well as techniques for abating pavement cracking. It will include contributions on theoretical modeling, experimental research, and case history studies on cracks in flexible, rigid, and composite pavements.
Topics:
- Initiation and propagation of cracks including modeling, calibration, and validation
- Top-down and bottom-up crack mechanisms
- Laboratory testing techniques and evaluation effectiveness
- In-situ experimental studies: field construction and rehabilitation techniques to inhibit pavement cracking
- Performance of crack preventative techniques and pavement service life prediction
- Construction approaches and their relation to crack development
- Crack surveys and nondestructive evaluation
- New design techniques

Objectives and Themes
The main objective of this Conference is to exchange innovation for the maintenance and the rehabilitation of all network assets, as road pavements, bridges, and tunnels, having in mind the user’ needs and expectations, and the integration of the required resources, promoting the truly transport infrastructure asset management.
The technical program includes keynote lectures on two subjects of relevance for the Conference objectives and sessions on following eight different themes covering the main concerns on asset management and pavement engineering:
1. Innovation in Materials, Practices and Technologies
2. Condition Evaluation of Assets
3. Assets Performance Models
4. Maintenance Measures and Guidelines for Roads with Low Traffic Volume
5. Maintenance Programming for Management Systems
6. Economic Trends for Management Systems
7. Implementation of Pavement and Bridge Management Systems
8. Road Asset Management
