Recycling Dredged Sludge in Asphalt Pavement

Journal of Materials in Civil Engineering, 2014
An experimental investigation of an innovative recycling method to reuse dredged sludge in asphalt pavements is presented. According to this method, semifinished products or agglomerates, made of dried sludge and bitumen, are produced. These products may be used to partially substitute fine sand and bitumen in the asphalt mix.

Different solutions for road pavement recycling

, 2013
Recycling of materials is becoming increasingly important for the Society due to the depletion of natural resources and the need to reduce the production of waste and its disposal in landfills. The present chapter comprises a series of studies carried out by the authors on different road pavement recycling technologies.

Advancing Pavement Sustainability with Recycled Materials

Journal of Civil Engineering and Urbanism, 2023
The increasing environmental concerns and depletion of natural resources have catalyzed the exploration of sustainable alternatives in civil engineering practices, particularly pavement construction. This study evaluates the efficacy of using recycled materials—crushed concrete aggregate (CCA), reclaimed asphalt pavement (RAP), and recycled plastics—as

Cold Recycling of Reclaimed Asphalt Pavements

2018
Pavement engineers have in front of them multiple challenges linked to addressing issues related to social development and society’s expanding needs. One of the most substantial of these issues is perhaps how to effectively rehabilitate and/or maintain the existing road network while preserving and sustaining limited natural resources.

Impact of recycled asphalt pavement material variability on pavement performance

Road Materials and Pavement Design, 2014
In recent years, recycled or reclaimed asphalt pavement (RAP) has been used increasingly due to its advantages in building sustainable pavement infrastructure. In the meantime, concerns have been raised regarding the performance of mixtures involving RAP.

Effects of higher percentage of recycled asphalt pavement on pavement performance

Road Materials and Pavement Design, 2013
The recycling of asphalt pavements has become a very routine procedure throughout the country. Research has shown that the recycled asphalt pavement (RAP) recovered from construction sites still contains usable materials, both in the recycled aggregates and recycled binder.

Recycled Clay Masonry and Recycled Concrete Aggregate Blends in Pavement

GeoCongress 2012, 2012
This paper presents the engineering characteristics of blends of recycled crushed clay masonry (RCM) with recycled concrete aggregate (RCA). The proportion by dry mass of RCM was 10%, 20% and 30% of the total mass. Results are reported of standard engineering classification tests, and static and repeated loading triaxial tests (RLTT) conducted by the ...

Structural recycling of pavement in Croatia

2011
Croatian example of cold recycling technology which was first applied in 2008 is presented through the rehabilitation of the state road DC 55 (from Vinkovci to Županja). The authors discuss the accomplished results and first experiences of pavement cold recycling technology in Croatia using foamed bitumen.

Hydraulic Properties of Recycled Asphalt Pavement and Recycled Concrete Aggregate

GeoCongress 2012, 2012
The saturated hydraulic conductivity (ksat) and water characteristic curves (WCCs) of three recycled asphalt pavements (RAPs) and three recycled concrete aggregates (RCAs) were measured. The ksat was determined using a constant-head, rigid-wall, 152-mm-diameter permeameter.
