In the world of road maintenance and paving, as well as construction, the issue of recovering material deriving from demolition and scarification is becoming increasingly urgent, with the dual objective of combining environmental protection with economic savings.
Those who work in the sector are well aware of the huge costs of transporting and disposing of asphalt and material from demolition, as well as the costs for the purchase and transport of new raw materials to the site.
The urgency from the market has also pushed institutions to accelerate the pace on the issue, which found a regulatory confirmation in 2022 End of Waste Decree (DM 152 of 27 September 2022).
The decree establishes that waste material resulting from construction and demolition subjected to recovery operations will no longer be classified as such, thus implementing a first important intervention for the circular development of the construction sector.
It is necessary to realize the sector features its own circular economy, particularly in regards to bituminous conglomerates: road paving can be recycled several times, in full compliance with the regulations in force.
As evidenced by the official data recently communicated by Siteb – the association that brings together the main operators of the road maintenance and paving industry and waterproofing membrane sector – almost 10 million tons of milled bituminous conglomerate are produced every year in Italy, which corresponds to approximately 18% of all waste from C&D (Construction and Demolition) 1.
CBA range: the importance of regeneration, crushing and recycling
In the light of the above considerations, Simex is expanding the crushing and recycling approach including the regeneration of all those materials which, once volumetrically reduced, screened or scarified, can be immediately recovered on site, in a sustainable and circular perspective, with both economic and environmental advantages.
From crushing to selective separation, from volumetric reduction to screening, Simex has a range of buckets for excavators and front loaders that facilitate demolition and recycling operations, directly on site, of waste material from construction sites and excavations.
Within the rich offer of buckets for recycling, the most recently introduced is the CBA range, specific for the crushing of asphalt slabs to a certifiable grain size.
The focus on the recycling of asphalt milling, more correctly called today bituminous conglomerate granulate by the legislation (called RA or RAP – Reclaimed Asphalt Pavement), begins from Simex expertise in the field of crushing and screening waste materials from demolition, combines the concept of milling drums with rotor crusher bucket technology.
The range of CBA asphalt granulator buckets is becoming more popular by the operators in the earthmoving and aggregates field and, to date, is available in three models: CBA 20, CBA 30 and CBA 40 for excavators from 12 to 40 tons.
The equipment features a cylindrical drum consisting of asymmetric teeth, driven by large displacement radial piston hydraulic motors, in direct drive. The rear grid determines the grain size of the material output and is available in several configurations, to meet the different characteristics required for the milled material by the regulations in force in various countries.
In recent months, several companies specializing in environmental services and management of aggregates deriving from C&D waste have relied on CBA buckets to volumetrically reduce large quantities of asphalt slabs, accumulated over time in their material storehouses.
The possibility of obtaining a certifiable grain size thanks to the rear grids allows the operator to create a milled conglomerate with different grain sizes (0-25, 0-30, 0-35 or 0-40 mm), depending on the size chosen and specific local regulations.
The advantages of CBA buckets: crushing to a certifiable grain size
The advantages are many. First of all, the evident reduction in costs, linked both to the purchase of new raw material and to its handling: significant costs for the transport and storage of material at disposal plants are avoided.
The on-site volumetric reduction of the removed asphalt slabs guarantees full truck loads and less heavy vehicles transports. Last but not least, the attention to the circular economy: recovering road bituminous conglomerate is sustainable and eco-friendly.
The certifiable granulometry of the output size allows to obtain a milled material that can be reused on-site or delivered to the appropriate bituminous conglomerate production sites, thus transforming a waste into a resource.
The CBA asphalt granulator buckets aim to ensure broad autonomy for operators engaged on a daily basis in road maintenance works, crushing aggregates and filling excavations for laying underground utilities.
Cutting down the time and costs related to transport, minimizing the purchase of new raw materials, means optimizing the logistical and economic dynamics of your site, while keeping a watchful eye on the issue of environmental impact and the recovery of those materials which, subject to specific local regulations, could be considered a resource and no longer waste.
