An Intelligent Compaction Analyzer: A Versatile Platform for Real-Time Recording, Monitoring, and Analyzing of Road Material Compaction

Abstract

Intelligent compaction (IC) is a technology that uses non-contact sensors to monitor and record the compaction level of geomaterials in real-time during road construction. However, current IC devices have several limitations: (i) they are unable to visualize or compare multiple intelligent compaction measurement values (ICMVs) in real-time during compaction; (ii) they are not retrofittable to different conventional rollers that exist in the field; (iii) they do not incorporate corrections for ICMVs reflecting variable field conditions; (iv) they are unable to integrate construction specifications as needed for performance-based compaction; and (v) they do not record all the key roller parameters for further compaction analysis. To address these issues, an innovative retrofittable platform with cutting-edge hardware and software was developed. This platform, called the intelligent compaction analyzer (ICA) platform, is effective at calculating conventional acceleration amplitude-based ICMVs and stiffness-based parameters and at displaying the spatial distributions of these parameters in a color-coded map in real-time during compaction.

Recent Development in Intelligent Compaction for Asphalt Pavement Construction: Leveraging Smart Sensors and Machine Learning

“…This approach aligns with the principle that the more intelligent a system becomes, the simpler its operation should be. However, the underlying technology behind IC is intricate and encompasses various disciplines [15,33,43,[48][49][50][51][52].…”

“…and ensuring that these data can accurately reflect the actual situation of the construction site. (2) Data preprocessing: The collected data often contains noise, missing values, or inconsistencies, which need to be cleaned and standardized through preprocessing steps [50]. This may include filtering out noise, filling in missing values, data normalization, etc., with the aim of making the data more suitable for model training and accurate prediction.…”

Operator guidance systems in road construction: a technological mediation perspective

“…It is important that compaction is carried out within an appropriate temperature range to avoid over- or under-compacting the asphalt layer (Bijleveld, 2015). To cope with this complex and dynamic process, asphalt machine operators rely on their implicit knowledge, craftsmanship, experience and rule-of-thumb approaches based on tradition and custom (Ranasinghe et al. , 2023; Zhang et al.…”

To cope with this complex and dynamic process, asphalt machine operators rely on their implicit knowledge, craftsmanship, experience and rule-of-thumb approaches based on tradition and custom (Ranasinghe et al, 2023;Zhang et al, 2019). A distinct absence of method-based approaches and a reliance on tacit knowledge create high variability in the overall quality of asphalt layers constructed (Bijleveld, 2015;Sivagnanasuntharam et al, 2023).…”

Instrumento Geogauge na avaliação de compactação do solo: uma abordagem de perícia ambiental

“…Tradicionalmente, a avaliação da compactação é realizada por meio de ensaios de campo, é canônico dentro de estudos de avaliação de compactação do solo os métodos de medição de cavas, métodos de raios nucleares, assentamento por laminação e compactação (Ranasinghe;Southararajah;Kodikara, 2023;Londynski;Ooi, 2022;Li;Airey;Feng, 2023). Todavia, existe uma enorme desvantagem entre esses métodos como, demanda de tempo, alto custo, baixa representatividade devido ao número inferior de amostragens e entre outros (Zhang et al, 2023).…”
