“…Several pavements have been tested at VTI during the 15 years of operation (Wiman 2001, Wiman and Erlingsson 2008, Oscarsson 2011. Structure SE10 (Figure 2) is mainly described here, but the structure was chosen as it represents a typical flexible pavement structure according to instructions given by the Swedish Road Administration (Vägverket 2004) and should therefore be used as a reference structure when designing new structures.…”

Flexible test road structures have been built and tested in accelerated pavement tests using a heavy vehicle simulator (HVS) at VTI in Sweden for 15 years. The objectives have been to investigate pavement responses and pavement performance behaviour, which can be used to validate mechanistic performance schemes. Here, the instrumentation is described, its accuracy is estimated, the response and performance are modelled and a performance prediction is carried out. The registrations of the measurements were rather smooth with acceptable variation. In general, good agreement was established between the measurements and calculations. The HVS machine can be used to evaluate new road concepts and maintenance strategies and provides the option of performing a life cycle cost analysis, which can decrease both costs and environmental impacts.

“…The surface wear rutting forms only in asphalt top layer, due to progressive loss of coated aggregate particles from the pavement surface, which is caused by combined environmental and tires influence [1], [23], [25]. This problem is not significant when usage of studded tires is controlled [1], [26].…”

Permanent deformation in asphalt pavement structures is one of the main pavement distress problems. The common asphalt pavement surface deformations are shoving and rutting at intersections, bus stops and line, in heavy vehicle loaded urban streets, where it is acceleration, deceleration, slow moving or static loading. Considering the occurred asphalt pavement layer rutting can be described as wear, structural and flow rutting. Recently, was observed the increase in severity and extent of rutting (the depth is 40 mm and more) in asphalt pavement structures in Vilnius city high-streets, bus lines and stops. The purpose of this research was to establish probabilistic (rutted) pavement structures in Vilnius city and to suggest the best treatment solutions. It was found that in many cases the failure was caused by asphalt layers fatigue and low resistance to flow rutting.

“…Pavement roughness influences pavement ride quality and usually leads to rider discomfort, increased travel times, and higher operational cost for vehicle. In the transverse direction of pavement, rutting along the wheel path hampers drainage characteristics, reduces runoff capability, and causes hydroplaning and loss of friction [3,4]. Longitudinal crack, which often occurs in deep ruts, induces the penetration of water and other debris, accelerates the rate of deterioration of HMA overlay and underlying PCC layer, and reduces the pavement service life [3].…”

Timely rehabilitation and preservation of pavement systems are imperative to maximize benefits in terms of driver’s comfort and safety. However, the effectiveness of any treatment largely depends on the time of treatment and triggers governed by treatment performance models. This paper presents the development of rutting model for overlay treatment of composite pavement in the State of Louisiana. Various factors affecting the rutting of overlay treatment were identified. Regression analysis was conducted, and rut prediction model is generated. In order to better predict the pavement service life, the existing condition of the pavement was also utilized through the model. The developed models provided a good agreement between the measured and predicted rut values. It was found that the predictions were significantly improved, when existing pavement condition was incorporated. The resulting rutting model could be used as a good pavement management tool for timely pavement maintenance and rehabilitation actions to maximize LADOTD benefits and driver’s comfort and safety.
