This study demonstrates the use of Class F fly ash in combination with lime or lime kiln dust in the full depth reclamation (FDR) of asphalt pavements. FDR, in the context of this paper, is a process of pulverizing a predetermined amount of flexible pavement that is structurally deficient, blending it with chemical additives and water, and compacting it in place to construct a new stabilized ba...

Traffic volume and vehicle load are one of the causes road damage. The research was conducted on Road Governor Soebardjo. objective to determine effect traffic standard loads method used is regression analysis correlation. This obtains relationship between (equivalent single axle load/ESA) damage with r P values. study results show a weight yields equation y = 6E-07x2 + 0.0038x 0.3849 robust co...

In almost all urban contexts and in many extra-urban conurbations, where road traffic is the main noise pollution source, the use of barriers is not allowed. In these cases, low-noise road surfaces are the most used mitigation action together with traffic flow reduction. Selecting the optimal surface is only the first problem that the public administration has to face. In the second place, it h...

Based on literature data, the paper analyzed impact of transport operational indicators related to quality road surface coverage safety. It presented results experimental studies effect adhesion cationic thermostable additive properties bitumen and asphalt concrete. The authors identified that introduction this leads an increase in viscosity softening temperature bitumen, its mineral materials,...

Assumptions of normality and independence are key assumptions made in the development and use of control charts. However for much industrial data, the assumption of independence is hard to justify. Control charts for the sample mean and sample standard deviation are obtained, when the observations are taken over a grid on a two-dimensional surface. It is assumed that the observations follow an ...
