Conf-paper-iscr

This paper describes the processes carried out in the crack and seat of an existing concrete pavement on the M40 Motorway in England.

The Use of Crushed Concrete Aggregate in Concrete for An Industrial Road at Ouffet

Conf-paper-iscr

In standard specifications 300 of 1994 (CCT 300) issued by the Ministry of the Walloon Region, permission is granted in the chapter dealing with cement concrete surfaces of roads belonging to roads with light traffic, to replace a maximum of 50 % of the granulates with crushed stones. The aim...

Prediction of Soil-Cement Strength Gain

Conf-paper-iscr

Prediction of the strength gain of soil - cement mixtures to be used as base or sub-base of roads is of practical importance. It is necessary to know with good approximation the strength developed under the 'in-Situ' curing conditions for a given age. This research work has studied the application...

Non-Clinker Slag Binder

Conf-paper-iscr

The solution of questions of using slag as a binder material vit1i different catalysts is highly actual, since it helps in broadening the nomenclature of binder materials. increases qualth' and durability of products containing these stags. Ecological problems of regions vitIi developed metallurgical industries are solved as well.

Thin White Topping in Vienna

Conf-paper-iscr

Conventional maintenance of rutted asphalt roads means resurfacing in short intervals or substitution of thick layers. Therefore, a new repair method was tested: Milling the top of the existing asphalt pavement, cleaning the surface and plaeing a dan layci of high performance concrete. The behaviour of the composite structure was...

Computer Aided Design for Flexible Pavements of Concrete Bricks

Conf-paper-iscr

This paper describes computer aided design (CAD) software and methods employed for effective design of flexible pavements with concrete bricks. Pavements consisting of concrete bricks allow many different patterns to be used. An area which is to be paved with concrete bricks is divided into a number of subdomains which...

The Belgian Experience with Stabilisation by Recycling in Situ with Cement

Conf-paper-iscr

The paper presents the progress to date of various worksites where stabilisation by recycling in situ with cement has been applied. This technique, which is the best way of recycling the existing road, consists in fact in mixing on site cement with the readily available crushed stones. It requires little...

Sand-Rich Concrete – An Alternative to Ordinary Concrete

Conf-paper-iscr

The natural raw materials gravel and sand are worldwide mined on a large scale. In many areas of Germany natural resources contain 70 % (and more) sand and less than 30 % gravel. Therefore in particular very fine sand often cannot be used and must be stored in waste disposal...

Repair of Concrete Pavements Using High Performance Concrete

Conf-paper-iscr

When heavily trafficed concrete pavements are being renewed, the work generally has to be carried out under considerable time-pressure. A newly developed, high performance repair concrete is ideally suitable for such repair work on account of its high early and final strength as well as its durability. It is produced...

Foundation Materials – Cement – Stabilised Quarry Sand

Conf-paper-iscr

When crushing stones of different calibres, quarries produce a large amount of sand, referred to as crushed sand. This material is often considered as a by-product and its use is reserved for less noble applications than road foundation. However, when stabilised with cement, this sand has very interesting properties and...

Sand-Concrete Pavements Gainful Use of Local Materials

Conf-paper-iscr

To complete the road between La Teste town and the famous , the Gironde Regional Council use the knowledge and experience requied during the national research and development project on sand concrete named SABLOCRETE to build a sand concrete slab pavement structure along 3,5 kilometres. The owners and engineers of...

A Study on the Thin Precast Concrete Pavement for Rehabilitation of Asphalt Pavements

Conf-paper-iscr

Precast concrete pavcmrnts have the merit to supply concrete slabs of good quality. In the concstructiori of precast concrete pavements, it is not necessary to use any special machines. And the special merit is that traffics can open immediatly because of unnecessary of curing. So this type of concrete pavement...
