New Standards in the Construction of Aircraft Movement Areas

Conf-paper-iscr

Airport runways and other aircraft movement areas are among today's most important infrastructure elements. The paper gives an introduction to general aspects of design and construction of concrete airport pavements, emphasizing the advantages of the two-course "wet on wet" placement technique. The above mentioned aspects are illustrated by the description...

Noice Reducing Exposed Aggregate Surfaces – Experience and Recommendations

Conf-paper-iscr

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...

New Concrete Pavement Structures in the Revision of the French Catalogue of New Pavements and in the Technical Guide of Overlays

Conf-paper-iscr

The documents for conception and design of new and reinforcement works on the French national road network were updated in 1988to take into account new pavement designs and techniques: dowelled slabs, continuously reinforced concrete, thick slabs on porous course, cement processed materials subbases. The article explains: - the development of...

Setting New Standards in the Construction of Flight Operation Areas in MUC 2

Conf-paper-iscr

The construction of the International Airport MUC 2 and especiallyof the flight operation areas in -for road designers- gigantic dimensions and short time-limit was a unique chance for the ex-perts to search for and find newstandards for tech-nique, economy and quality by an innovative fur-ther development of proven equipment and...

Porous Urban Pavements in Cement Concrete

Conf-paper-iscr

Questions regarding the environment are being particularly felt in certain countries, and noise con-trol requirements have led to the development ofthin free draining materials able to limit tirepavement contact noise.We shallbe dealingherenotwith a thin free draining pavement structure, butwith a porous concrete pavement of 40 cm thick-ness. Theoretical studies have...

Dynamic Deflection Measurement on Rigid Payements Using the Falling Weight Deflectometer

Conf-paper-iscr

Deflection caused by a load is an important measure for the bearing capacity of rigid pavements, too. For this reason the deflection on a variety of sections with different constructions has been measured in the Federal Republic of Germany. For these measurements the «Falling Weight Deflectometen> was used, developed by...

Concrete Structures Made of One Piece Lean Concrete Slabs French Experiments and Pavement Design – Future Developments

Conf-paper-iscr

France has an extended experience in hydraulic binder treated materials: in semi-rigid structures, in cement concrete thick slabs, in lean concrete for concrete pavement subbase layers. It has permit-ted to establish a new and very competitive struc-ture: the lean concrete thick slab on a drainingcourse with or without tranverse joints.A...

Concrete Continuously Reinforced with Flat_ Slotted_ Galvanised Steel Strips. Experience of FLEXARM Reinforcements. French Road Network 1986-1989

Conf-paper-iscr

The dream of concrete pavement constructors, to replace the conventional difficult-to-fix reinforce-ments, which require a considerable manual work-force, with a continuous bobbin-wound reinforce-ment, has today become a reality. The chosensolution was a weldable carbon steel, with an elas-ticlimitgreater than 700MPA, a rectangular cross-section 40 mm x 2 mm, slotted for...

Developments in Noise Redution of Concrete Roads in the Netherlands

Conf-paper-iscr

In the Netherlands experiments have been performed recently :onceming noise reduction on concrete roads. Three pos-.ibilities are being investigated:I. Top layer of no-fines porous concrete.~. Surface of washed dense concrete.. Dense concrete with fine-grained epoxy surface treatment. noise emission level slightly higher than on porous asphalt,iut much less than on...
