Concrete Pavements in Seasonal Frost Conditions – Finnish Experience of the Durability and Economy of a Concrete Pavement Built in 1990 in Northern Finland

Conf-paper-iscr

Oulu is a city of about 145,000 inhabitants including its suburban area located in northern Finland where the winter can be very cold. The freezing index is about 40,000 °C h (once in 10 years) and the frost penetration depth can be about 2 m or rluuue. lii 1990, 4...

Use of Fast Track Concrete Construction in the USA

Conf-paper-iscr

Fast track concrete pavement technology provides alternatives that can meet the public's demand for quick access to quality pavements. Fast track concrete pavement construction entails any method of accelerating construction. Some changes in tradicional use and consideration of certain aspects ot concrete pavement construction accompany fast track. However, fast track...

Concrete a Material for Urban Development

Conf-paper-iscr

These last years, the development of the road network in urban areas of France has taken a new direction. The aim is to improve the users safety as well as the traffic conditions. This new trend requires a geometrical development of urban areas, with regard to safety, aesthetics, intcgrotion into...

Factors Affecting the Abrasion Wear of Concrete Pavements

Conf-paper-iscr

This paper describes the application of a relatively simple and inexpensive laboratory test deiived Iiuiii ASTM procedure C779 for evaluating abrasion resistance of concrete surfaces. Factors affecting the reproducibility and precision of the test are quantified. The paper describes the use of the test to evaluate trial mixes of paving...

Restraint Stresses in Young Concrete Pavements

Conf-paper-iscr

Under adversè conditions, the restraint stresses of young concrete pavements can cause the forma-tion of random cracks. In order to determine theparameters which influence the formation of thesestresses a full-scale experiment including sixdifferent test sections was performed. The experi-ment showsthe greatinfluenceof climaticconditionsin the days after placing the concrete. The analy-sis...

The Influence of Size and Hardness of Sand Particles and their Proportions on the Skid Resistance of Cement Mortars

Conf-paper-iscr

irnestone and emery sands divided into 6 fractions, were used ,cast cement mortar specimens in PSV moulds. After 28-day ater curing the specimens were subjected to accelerated ilishing and their Skid Resistance Value (SRV) was measured ith the pendulum tester. Specimens of 100 % limestone or )0 % emery sand,...

Concrete Setis a Functional and Rational Technique

Conf-paper-iscr

The use of concrete setts in France has been growing for a decade, especially on urban roads. This technique, inspired by stone setts, but also by such precast concrete products as kerbs and gutters, very quickly generated needs: for design methods, for standardization of the product, for rules for use....

Structure Analysis of Roller Compacted Concrete Pavement

Conf-paper-iscr

Roller Compacted Concrete Pavement in Japan has progressed rapidly today because of its simplified paving method and early opening to traffic. Structural properties of RCCP are required to be investigated to establish design method of this pavement. Load response after paving and strain due to base course friction were measured....
