State 和 federal agencies often require that those working on their construction projects have a higher level of expertise, 经验, 并持有相关技术人员资格证. 授予道路和其他基础设施项目合同的, 政府, 和私人, may also require that the contractor awarded the project only use workers with a specific certification(s).
集合技术员认证的检测方法必须符合 ASTM C1077 测试标准: St和ard Practice for Agencies Testing 混凝土 和 混凝土 聚合 for Use in Construction 和 Criteria for Testing Agency Evaluation. The testing agency must adhere to all criteria within C1077 with services provided "under the technical direction of a registered professional engineer.“此外, those pursuing a Level 1 certification must have a solid grasp of the following aggregate st和ards:
|粒度大于75 μ m (No. 通过洗涤筛分矿物集料||T 11||C117|
The American 混凝土 Institute appears to be the only industry testing organization that offers national aggregate technician certification programs that are specific to testing operations. 然而, 还有许多其他的测试机构, 学院和大学, 行业协会, 和 state departments of transportation throughout the country that offer preparation materials 和 study resources, 培训, 和/或测试. There may also be an industry-related company in your area that partners with a state aggregate association to provide classroom 和 h和s-on lab 培训 in preparation for the certification exam.
吉尔森和俄亥俄聚合有持续的关系 & 工业矿物协会(OAIMA)，我们通过它主办了OAIMA的 为期两天的培训和测试课程 为参加者作好准备 俄亥俄州二级综合技术员认证. This two-day 培训 event is the same required by Ohio DOT of 聚合技术人员, 和 meets Part 637 of the Federal Highway Administration (供料) Code of Federal Regulations regarding "qualified" sampling 和 testing persons.
- 从国家层面开始: As stated earlier, ACI offers 培训 和 national certification 考试 for 聚合技术人员, many of which go h和-in-h和 with many concrete technician certifications. 注意随着技师认证等级的提高, there are additional st和ards that the applicant must be well-versed in. The links in the chart below take you to the respective ACI pages with these st和ards, 以及ACI学习材料等信息.
|聚合测试技术员:1级 工作任务分析||"An individual who has demonstrated the knowledge 和 ability to properly perform, 记录, 和 report the results of basic field 和 laboratory procedures for aggregates.”|
|2级综合测试技术员: 具备ASTM/AASHTO标准知识||"An individual who has demonstrated the knowledge 和 ability to properly perform, 记录, 和 report the results of advanced laboratory procedures for aggregates.”|
|骨料/土基测试技术员 具备ASTM/AASHTO标准知识||"An individual who has demonstrated the knowledge 和 ability to properly perform, 记录, 和 report the results of basic field 和 laboratory procedures for aggregates 和 soils."|
- 国家ACI训练 & 考试程序: 联邦消防局的名单 国家交通网站 你可以开始了吗. Your state department of transportation (DOT) will have its protocols on technician certification, 特别是在联邦法规要求之外. 另外, 即使不是全部，也是大部分, state DOTs offer technician 培训 programs 和 certification exams through the agency itself or in partnership with a state-approved entity. Bear in mind that a State DOT may also require a related concrete or asphalt technician certification, 与聚合认证一起使用, 对于那些在交通建设项目工作的人来说.
除了国家机构, colleges 和 state universities often have technical programs geared to aggregate technician certifications. The information below can guide you further in knowing what to search for 和 what else to keep in mind:
- 搜索 for aggregate technician certification on your state DOT website to see what exists. 例如, the Arizona DOT takes you to the Arizona Technical Testing Institute link, ADOT的一个部门负责监督日程安排, 调度, 学习指南, 考试, 注册技术员名单, 和更多的.
- 再一次, it's not uncommon for a state DOT to require an aggregate technician certification in addition to the asphalt or concrete certification. 例如, Colorado requires a Level-E Aggregate 认证 of those who determine characteristics of aggregate used in asphalt mixtures for state projects. CDOT与LABCAT合作, 供料, 和 other entities on certification; criteria include a demonstrated proficiency in aggregate sampling, 砂相等, 细骨料未压实的空隙率, 骨料比重的测定, 和更多的.
- 类似的, the Oregon DOT Certified Aggregate Technician (CAgT) program is a joint effort with the 沥青 Pavement Association of Oregon. State specifications require a CAgT to conduct quality control testing during the production of aggregate materials used in HMAC, EAC, PCC, 基层和肩料, 芯片海豹, 油垫, 以及其他高速公路应用. 除了注册聚合技术员, they offer an exp和ed Greenhorn version of the certification program for those new to the industry.
- Many universities 和 technical colleges work cooperatively with their state DOT to provide certification 培训 和 testing. 例如, Michigan DOT offers Aggregate 认证 Level 1 through Lawrence Technological University, while Wisconsin DOT 和 the University of Wisconsin-Platteville together offer three aggregate technician certification programs. Also searching universities in your state for aggregate technician certifications will help you find out what else is out there.
学习指南并不缺乏, 有预考的培训计划, 和ASTM的考试地点, ACI, 国家高速公路研究所, 国家机构, 或学校. A Google search of 培训 materials for aggregate technician certification came 回来 with several links, 其中有:
- ASTM 聚合测试e -学习包 和 聚合基地培训- E-Learning Bundle (每年更新一次)
- 国家高速公路研究所 aggregates-related课程
- 全国沥青路面协会， 在线研讨会,和手册
- ACI 书店, ACI大学在线学习, 聚合上的免费在线演示
最后, 启动流程时, do your homework prior to registering for an in-person or online 培训/CE courses from a private 培训 entity. 以下是一些需要考虑的问题:
- Does the 培训 program encompass all ASTM/AASHTO st和ards required for the specific certification?
- Does it specifically prepare for the aggregate technician certification exam from a nationally-recognized testing agency such as ACI or a qualified agency in your state?
