For the time being the exposed aggregate technique is the cheapest way of building a rigid pavement with a surface that is noise reducing, skid resistant and durable. The technique requires the use of specially adapted payers, very good-natured retarders and a very efficient curing. Special combinations of surface retarders...

The design of jointed concrete pavement (JCP) using mechanistic-empirical concepts must incorporate a systems approach in considering material and traffic variability with respect to design and calibration in a mathematically consistent manner. Calibration procedures are necessary to insure the prerequisite accuracy in the design calculation and estImate of pavernelil. peIIuIIIIdlIlx....

This paper considers the role of whole life costing in the management process for the road network and explores the background to current interest in England. It describes the development of the computer model, COMPARE, for assessing the whole life costs of bituminous and concrete pavement options. The key components...

As precast prestressed concrete pavement slabs with high strength are resistant to abrasion and enable fast construction, they have been increasingly used in Japan instead of the conventional pavements, especially in heavy traffic roads and airfields. 1-lowever, in precast prestressed concrete slab pavements with plenty of dowelled joints, pumping and...

Reconstruction of concrete pavements can be performed by fracturing the existing concrete slabs into small pieces in situ and then placing a leveling course and overlay. The fractured slabs provide a firm base for the new pavement. The technique is increasingly used for the reconstruction of concrete pavements where the...

The changes in the landscape happened during the last 40 years due to human activity have produced a slow change of mind. Therefore it is no wonder that also for road construction nature is taken more into account. The Concrete wheel track is a compromise. Firstly it prevents from covering...

The continuously-reinforced semi-rigid structure consists basically of a thick structural layer placed directly on the foundation when it is made of untreated, permeable materials, or on a draining layer of geotextile when it is treated. This layer is made of concrete having a low cement content and cracking is rnntrnlled...

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...

At the Brussels National Airport, important expansion works, mainly new taxi-lanes and platforms have been underway since 1989 in accordance with the masterplan "Zaventem 2000". For the new platforms, almost 500.000 m 2 will be paved with a 35 cm thick high quality concrete pavement. By the end of 1993,...

In 1990 a technique for building pavements with a noice reducing concrete surface was developed in Austria. The top layer contains aggretate with 8 mm maximum size. The surface is sprayed with a retarder and brushed the next day to expose the aggregate. This technique has been used on 120...

This article presents the design criteria and operating procedures adopted for the installation of the instrumentation devices to record the variations in "sIowIy changing quantities affected by temperature and humidity as well as by traffic-induced dynamic" phenomena. Interesting trends and correlations between the various physical quantities measured have been found....

In this paper we discuss about how to select the best pavement type to minimize the pavement cost. It is studied which pavement type (flexible or rigid pavement alternatively) is more suitable for Turkey taking into account economic criteria. The most important parameters for choosing the type of pavement are...
