The American Concrete Pavement Association presents distinguished service awards in recognition of people and practices that represent the very best the transportation construction community has to offer The award program was established in 1968 when the Association s first honoree was James W Johnson Iowa Highway Commission Testing Lab
Procedures to perform structural design of pavements are detailed in various design guidelines Even though the recommendations may be different across the different guidelines some of the underlying principles are similar The present paper briefly reviews various pavement design guidelines on structural design of asphalt pavements with reference to the
Sustainable and resilient pavement infrastructure is critical for current economic and environmental challenges In the past 10 years the pavement in…
The aim of this study is to evaluate the mechanical and environmental behavior of mortars containing fly ash from de inking paper sludge combustion PS FA as secondary cementitious material
Concrete plays a vital role in the construction of structures like roads bridges buildings dams etc It consumes huge amounts of energy to process raw materials like limestone shale and clay into cement for huge structures like roads 350 425 kg/m 3 [] Due to depleting limestone reserves it has become omnipotent to use supplementary cementitious material SCM in
used at 10% 20% and 30% cement replacement levels with the aim of reducing the cement consumption in concrete and the effect of the GGBS on the workability compressive and flexural strength was investigated The PQC Pavement Quality Concrete containing GGBS was also found to have 20 30%
Breaking the adhesion between ice and pavement is crucial for road de icing This study investigates the impact of concrete pavement surface characteristics on ice pavement adhesion To achieve this 20 cement concrete specimens with different combinations of 10 surface textures and 2 wettability surface characteristics were prepared
Self compacting concrete SCC is one of the most significant advances in concrete technology over the past two decades SCC was developed to ensure adequate compaction through self consolidation and facilitate placement of concrete in structures with congested reinforcement and in restricted areas This paper aims to focus permeability study of
The reliability of the pavement design performance process is the probability that a pavement section designed using the process will perform satisfactorily over the traffic and environmental conditions for the design period AASHTO 1993 [1] In other words there must be some assurance that a pavement will perform as intended given

to achieve a particular type of stabilised material mix design This part of the Guide to Pavement Technology does not detail quality control aspects of manufacture or performance attributes of stabilised materials nor the sa fety aspects of using specific binders
In concrete pavement brick if basalt powder consumption and cement consumption was reduced by 5% the overall environmental impact would be reduced by % and % and the production cost would be reduced by × 10 −1 RMB and × 10 −1 RMB respectively In permeable brick if the consumption of cement and crushed gravel was
The former study Ali et al 2020 also showed that glass fibre reinforced RCA pavement required 45 55 mm lesser depth of concrete pavement versus NA pavement for a major arterial street using the PCA Mechanistic Design Method Packard 1984 due to the improved flexural strength and less brittleness In addition a slight thickness

sand with Stone crusher powder Strength behavior of concrete with the use of stone crusher powder as a replacement of fine aggregates in different proportions is discussed Test results are also discussed pertaining to strength and values are compared with conventional concrete Keywords Degradation of rivers Environmental impacts Stone
The concrete crack width concrete crack spacing and rate concrete temperature concrete strain and GFRP bar strain behavior were recorded and investigated The GFRP CRCP and a 94 m long stretch of steel CRCP on that highway were compared in terms of

This paper presents the feasibility of the usage of Quarry Rock Dust as hundred percent substitutes for Natural Sand in concrete Mix design has been developed for three grades using design an
resulting pavement will be at least as strong as the flexible pavement that would have been produced using the FAA design charts This is in fact a conservative structural design method since research on concrete pavers and bedding sand have shown such pavements to have load distribution characteristics greater than
